Build PhabricatorTagView
Summary:
Builds out most of the non-hover-stuff from overview-hovercards.png. Things I didn't build:
- Tokens (I like them a lot but don't want to scope creep)
- Functions (backend mess / future work)
- Icons for tags.
- Tags with pointy ends and holes in them (an earlier mock had this I think but they're gone on final)
- The cyaney color for "Sporadic" since I just noticed it while typing this up.
Test Plan: Looked at UIExample page.
